- Single file include,
- Included in-browser template compiler if you wanted it (plus the option to write view functions manually)
- Comprehensive Documentation that you could read through in a hour
- Reasonable embrace of HTML, CSS, and JS as separate tools. For example, most of the reactivity system is managed in JS, but the integration with HTML components is excellent -- nothing crazy like passing all your variables through a single `data` attribute on a <div>.
Vue seems to be working hard to build a moat of complexity around itself. I think it all started with the introduction of .vue files. I personally don't understand the need to put 3 different languages in the same file. Vue CLI is another step in the same direction of adding complexity. It looks like simplicity because "oh it's so easy for new people to get started", but if this keeps going, you're going to get tons of people who don't learn the basics/don't understand how the underlying tools work/can't fix problems in their own codebase because they didn't write the first 20% of it.
I still love Vue but I'm very very skeptical that this complexity they're adding isn't going to snowball, and eventually vue-cli will be the only supported way of creating vue apps, with some of the features that keep Vue simple being removed because they "prevent" progress.
Also, Vue CLI is not a game changer. Frontend frameworks all seem to have their own CLIs now, which is baffling in-and-of itself on the face of it.
